Commentary Han Hoa Military Magazine in April, a leading source of military technology expert reputation in Moscow (Russia) said that under a bilateral agreement signed between Russia and Vietnam, in 2013, Vietnam will receive the first Kilo submarines, a year later as the second and the last one will be delivered in 2017.Compared with 636-MK submarines that use by the Chinese Navy, Kilo 636-MV submarines that Russia sold to Vietnam has many differences, of which the largest is about armament.

On the periscope, both Kilo 636-MK submarine and Kilo 636-MV submarines are equipped with sounding optical system, but the periscope used for tasks Kilo 636-MV attack submarines are installation of additional equipment measuring distance from IR ray and TV monitoring systems, Meanwhile, Kilo 636MK submarines primarily use optical aiming device and no distance measurement beam from. That means fighting capability at night and the attack accuracy of the Kilo 636-MV submarine will be higher than Kilo 636-MK submarine.
